And AC can heat too! For example, in some EU countries gas boilers are still a huge thing, even though increasingly archaic. At the same time many of its users denounce AC because of reasons, apparently missing the fact that an AC is an (air-to-air) heat pump. Incredible how Big Boiler somehow convinced people to keep heating their houses by burning gas in these contraptions while ACs could do the job with much higher energy efficiency while also cooling the house in summer (and yes many places with these gas boilers have _hot_ summers these days)!
- margor 1mo agoIt's not that simple. If you have a gas boiler, you're most likely exchanging heat using radiators which are _designed_ for certain amount of heat exchange. With high water temperature, you can get away with smaller radiator and deliver the same amount of heat. The story gets worse when you put heat pump to the same system - now you have to run it to its limits to have just enough heat in the water to make the radiators release enough heat to barely heat up the room. Of course, it's only that simple to replace one heat source with another, why wouldn't anyone do it already?

In most European countries, electricity is taxed much higher than gas. Those taxes eat a large chuck of the efficiency gains from a heat pump, and then it's not worth the effort.
